Final answer:
To calculate how many inches a 20-inch diameter tire rolls in one turn, compute the tire's circumference using the formula C = πd and find that it rolls approximately 62.83 inches per turn.
Step-by-step explanation:
To find out how many inches a 20-inch diameter tire rolls in one turn, you need to calculate the circumference of the tire. The circumference is the total distance around the outer edge of the tire, which can be found using the formula C = πd, where π (pi) is approximately 3.14159, and d is the diameter of the tire.
For a 20-inch diameter tire, the calculation would be:
C = π × 20 inches
C = 3.14159 × 20 inches
C = 62.8318 inches
Therefore, a 20-inch diameter tire rolls approximately 62.83 inches in one turn.
